Force View Number Data Type Precision?
Aug 18, 2011
I am working on an application that pulls data from an Oracle view into Microsoft Excel (Oracle 11g, MS Excel 2003). It is an automated pivot table created through vba. The problem I'm having is that the decimal points from number columns are being truncated - they don't make it to the pivot table.
When I use the pivot table wizard and set the external data source using a SQL string (select * from view), the precision is not lost. When I create the pivot table automatically in vba, the precision is lost. The pivot table settings, regardless of how the data is brought in, shows the format of the number column as general. This tells me that Excel is trying to figure out what the data type is, and can't (not smart enough).
When looking at the description of the view, the data type is NUMBER (no precision). The table that it is pulling from has the precision set (NUMBER(11,3)). I have tried using the following, but it doesn't work:
select to_number(field_name, '99999999.999') field_name from view

I have a procedure. Here is the spec
Procedure countyname(i_lat IN Number, i_lon IN NUMBER, o_countyname OUT VARCHAR2);
The procedure works fine when the input parameter values are small precision like 30.653, -618.765 etc.it fails if the Input parameter values have more precise like 35.694872140886...I think the IN Number can only take upto certain precission.
Is there any way I can specify the precision for a NUMBER input parameter in a procedure?
ex: Procedure countyname(i_lat IN Number(30,10), i_lon IN NUMBER(30,10), o_countyname OUT VARCHAR2);
when I tried the above statement it doesn't compile it gives PLS-00103 error.

We have truncated number based on the decimal value. i tried to truncate number based on the precision using cast function. i got an error "value larger than specified precision allowed for this colum".
create table TEST_NUMBER
(id number(4,1));
insert into TEST_NUMBER
values(1234.789888888888);
[code]...
ORA-01438: value larger than specified precision allowed for this column
01438. 00000 - "value larger than specified precision allowed for this column"
*Cause: When inserting or updating records, a numeric value was entered that exceeded the precision defined for the column.
*Action: Enter a value that complies with the numeric column's precision, or use the MODIFY option with the ALTER TABLE command to expand the precision.
i want result like 1.8

POWER(47.3616, 27.1261) returns: 2.80403309600359E45 which causes "number precision too large" error in my variable which is defined as NUMBER(20,20).
I've tried ROUNDing and TRUNCing the product, but still get the same long output. The only thing that seems to work is SUBSTR.
Is that the ONLY way to deal with this? It seems like there would be a better way or is there another type I should use these super long decimal results?

There is a text item on my form with NUMBER data type. I want to force the user to enter exactly 3 digits in to that text item. My current FORMAT MASK is set to 990. But this allows user to enter even a single digit where as my requirement is user should enter exactly 3 digits. Can we achieve this by changing the FORMAT MASK property?

we use oracle 11g. 11.2. I have a situation where in a pl-sql package, there is a modification needs to be done . Every User is associated with destination codes. For eg, user1==>0101,0104 There is a destination_number and country field in the table1.Each of the destination number is associated with a country code and this combination is unique. for eg:
dest_code country_code 0101 CHINA 0202 UK 0101 Mexico 0104 Mexico
For example, if user1 logs in to the system, then pl sql logic will look if that dest_code is in a table1,If the dest_code is present in the table1, then that dest_code number wont be added to the dest_code list formed for that user. For example,if user1 got dest_codes 0101,0104 associated with him.IF 0101 is in exception table then 0101 and 0104wont be used to form dest_code list. If NOT, a dest_code list will formed like 0101||0104. I am able to form the logic like I have a cursor that loops for each dest_code.For each dest_code , it will get that dest_code into v_dest_code_no number type variable. open cursor fetch dest_code no into v_dest_code v_dummy number:=0;v_dest_code_list number:=0; LOOP v_dest_code_list:=v_dest_code ||v_dest_code ; v_dest_code :=0; END LOOP: How to make sure that for each dest_code set, if one of them is in table1, then the next number also will not be added to the list.

I'm trying to use MULTISET UNION to append several collections into a single recordset.The select queries shown for the CURSOR are simple beta versions of the real queries which have about 350 fields to each of them. I will be appending data from 15 of these queries which each will with no more than 20 records per query into a new single recordset (not sure if 'recordset' is the correct phrase or term for what I mean, it could be ARRAY, OBJECT, COLLECTION or something else all together).
Here is text of the ERROR message:
ORA-06550: line 63, column 1:

PLS-00487: Invalid reference to variable 'VARCHAR2'
ORA-06550: line 71, column 5:

I've created a stored procedure which creates itself a view (a MV to be honest); the instructions to create this m.view are dinamically built insinde my procedure, so each time i run it, based on the different input parameters, i've got a different result (my output m.view can have three colums the first time, or ten the next time) how can I read my output view to put the data into file? I've tried with "select * bulk collect into my_array from my_ output_ view"...after declaring "my_array" as a varying array with the max number of colums I could ever have...but nothing: if the array dimension doesn't match the number of columns that i've on my view, i.e. i receive "ora-00947 not enough values" error.
Is there a method to dimension dinamucally the array to store my data? Or should I change the code to fetch some other way the data i need to put to a file?

I got the error "ORA-06502: PL/SQL: numeric or value error: number precision too large" while assigning a value to variable.
For example var Number(5,3);
var:=225.345
Here it should give this error since the no.of digits before decimal should not be more than 2.
In of the procedure, I am getting this error.
Is there any way can we check this violation before assigning this values to a variable?
For example, if the value is too large, we can give a default value etc before assigning it.
Environment: UNIX AIX - 5.3, Oracle 11.2.0.1

When we are trying to create number data type column of a table with precision greater than actual value,it's accepting the definition of the table . But we are unable to insert any values into the table.how internally it stores the value
SQL> drop table precision_test;
Table dropped
SQL> create table precision_test(name number(2,5));
Table created
SQL> insert into precision_test values (1);
insert into precision_test values (1)

Using DB 10.2.0.5, I've encountered a strange behavior today while trying to compare ORA_ROWSCN with a previous SCN stored in a column.
SELECT
h.id HID,
h.ora_rowscn HSCN,
o.id OID,
o.scn OSCN,
[code]......
1157 rows While casting o.scn to a number gives me another resultset (this one is correct):
SELECT
h.id HID,
h.ora_rowscn HSCN,
o.id OID,
o.scn OSCN,
h.ora_rowscn-o.scn DIFF
[code]......
2114 rows I got the same result if I use NVL(o.scn,0) rather than TO_NUMBER(o.scn). I can't find out why this happens. Obviously, the ">" condition doesn't match when the difference is too small.
AFAIK, ora_rowscn is a NUMBER while my "scn" column is a NUMBER(12) (which should be sufficient to store my DB or remote DB's SCN).

But when I run this script I get exception : 'ORA-01438: value larger than specified precision allowed for this column'.
I have checked in my soucre table as well as in inserting table, everything looks fine to me.

I have the following query:
Select
tag0.TAG_VALUE pid, tag1.TAG_VALUE, tag2.TAG_VALUE From TAGGER.TAGGABLE_RESOURCE r
, TAGGER.TAG tag0
, TAGGER.TAG tag1
, TAGGER.TAG tag2
where 1=1
[code]....
This runs in about 400ms. Now I replace this:
ANDtag0.TAG_TYPE in (4602, 5228)
ANDtag1.TAG_TYPE in (4612, 5225)
ANDtag2.TAG_TYPE in (4613, 5226)
with this:
ANDtag0.TAG_TYPE in (select COLUMN_VALUE from ( select * from table( TAGGER.GET_IDS_OF_SIMILAR_TAG_TYPES('Patient ID') ) x1 ))
ANDtag1.TAG_TYPE in (select COLUMN_VALUE from ( select * from table( TAGGER.GET_IDS_OF_SIMILAR_TAG_TYPES('Patients Sex') )x2 ))
ANDtag2.TAG_TYPE in (select COLUMN_VALUE from ( select * from table( TAGGER.GET_IDS_OF_SIMILAR_TAG_TYPES('Patients Birth Date') ) x3 ))
So instead of hard coding the IDs there is a function that looks them up. The function itself is reporting that it runs in 0ms. But when I run the new query:
Select
tag0.TAG_VALUE pid, tag1.TAG_VALUE, tag2.TAG_VALUE From TAGGER.TAGGABLE_RESOURCE r
, TAGGER.TAG tag0
, TAGGER.TAG tag1
, TAGGER.TAG tag2
where 1=1
[code]....
it takes around 6s to run. I have looked at the explain plans it it seems as though the function based approach is triggering a full table scan of 'TAG'.
I have tried it with query hints to use index, but it doesn't change the execution plan, or the query time.
The explain plan for the quick query is:
PLAN_TABLE_OUTPUT
---------------------------------------------------------------------------------------------------
Plan hash value: 1031492929
---------------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
[code]....
And the slow one is:
PLAN_TABLE_OUTPUT
----------------------------------------------------------------------------------------------------
Plan hash value: 2741657371
----------------------------------------------------------------------------------------------------
| Id | Operation | Name | Rows | Bytes |Te
----------------------------------------------------------------------------------------------------
| 0 | SELECT STATEMENT | | 20M| 1602M|
